Yeah, does anyone have a news source for this besides the one twitter thread? Wikipedia wants to know.
Anything he says is reliable, but by all means wait for other confirmation.
WRT wikipedia, I have a story about the Richard Guy page, but that's not a story for here. Another time.

So I imagine the mods granted the black bar in part on the strength of who posted it. They don't do so lightly and have been known to put a hold on threads in the past to wait for confirmation. They haven't chosen to do so this time and there is likely a compelling reason for that.
